Can Police Take My Phone? Your Rights Explained

When Can Police Take Your Phone?

Police do not have an unlimited power to take your phone whenever they wish. The power depends on the situation and the specific statutory authority being used. In practice, phones are most commonly seized in connection with arrest and search powers under PACE.

On Arrest — Search of Your Person

If you are arrested at a place other than a police station, a constable may search you where they have reasonable grounds to believe you may have concealed evidence relating to the offence, or items that could assist escape or cause injury. Anything found which is evidence may be seized.^[1] Your mobile phone falls within this if the officer has reasonable grounds to believe it may contain evidence (for example messages, call logs, location data or photographs relevant to the investigation).

At the Police Station

If you are brought to or arrested at a police station, the custody officer may search you and seize property where they have reasonable grounds to believe it may be evidence relating to an offence, or that you may use it to cause injury, damage property, interfere with evidence or assist escape.^[6] A phone needed as evidence may be withheld rather than returned to you when you leave custody, in accordance with PACE Code C.^[9]

Search of Premises After Arrest

Where you are under arrest for an indictable offence, a constable may enter and search premises you occupy or control if they have reasonable grounds for suspecting there is evidence relating to that offence (or a connected indictable offence) on the premises.^[2] This generally requires written authorisation by an inspector or above, subject to exceptions in section 18. Phones found during such a search may be seized under section 19 where the constable has reasonable grounds to believe the item is evidence and seizure is necessary to prevent it being concealed, lost, altered or destroyed.^[3]

Other Search Situations

Phones may also be seized during searches carried out under a warrant, or in other situations where a lawful search power applies and section 19 is engaged.^[3] If you are attending a voluntary interview and are not under arrest, the position is different — police may not have the same automatic power to seize property from you. If officers ask for your phone in a voluntary setting, ask what power they rely on and take legal advice before handing it over.

Property in Police Custody

When you are detained at a police station, the custody officer is responsible for recording your property. PACE Code C sets out how personal property — including electronic devices — should be recorded, stored and dealt with while you are in custody.^[9] Items needed as evidence may be retained rather than returned to you when you leave custody.

Seizing Your Phone vs Examining Its Contents

It is important to understand that seizing your phone and examining what is on it are not the same thing. Police may lawfully take physical possession of your device under PACE search and seizure powers, but accessing the data inside — particularly where the device is locked or encrypted — may require additional steps.

In many cases, phones are sent to a digital forensic unit for examination. This can involve downloading call logs, text messages, WhatsApp conversations, photographs, location history, internet browsing data and material from apps. The Attorney General's Guidelines on Disclosure (Annex A — Digital Material) set standards for how digital evidence should be handled in criminal cases.^[12]

Police may also seek data held remotely — for example in cloud backups or by service providers — using separate legal powers. That data is not necessarily on the physical device, but may still be relevant to an investigation.

Do You Have to Give Your PIN or Password?

General Position

There is no general common-law duty to help police unlock your phone. If an officer simply asks you to enter your PIN, passcode or biometric unlock, you are not automatically obliged to comply. However, refusing may mean police cannot access the data without other means (such as forensic tools or a formal legal notice).

Do not guess or speculate. The correct response depends on the exact power being used and your individual circumstances. Always get legal advice before disclosing passwords or unlocking a device.

The RIPA Section 49 Notice

Under Section 49 of the Regulation of Investigatory Powers Act 2000 (RIPA), certain public authorities can give a notice requiring a person to disclose a key or password to protected information (such as encrypted data on a phone) in specified circumstances.^[7]Authorisation is governed by Schedule 2. For material seized by police under a statutory power, a Circuit judge's permission is not always required — a constable of superintendent rank or above (or with permission from such an officer) may have the appropriate permission to give a section 49 notice.^[11]

Section 53 makes it an offence to knowingly fail to comply with a section 49 notice by not disclosing the key or password when required.^[8] This is a serious matter. If you receive a formal section 49 notice, you should take urgent legal advice before deciding how to respond.

A solicitor can check whether the notice is valid, whether the authorisation is in place, and whether there are grounds to challenge it.

How Long Can Police Keep Your Phone?

PACE section 22 provides that anything seized by a constable in the exercise of a power of search or seizure may be retained so long as is necessary in all the circumstances.^[4] In practice, this means your phone can be kept for the duration of a police investigation — which may be weeks or even months — if it is needed for forensic examination, as evidence at trial, or in connection with an offence.

Section 22(4) provides that where a photograph or copy would be sufficient for investigative or evidential purposes, the original should not be retained.^[4] PACE section 21 also allows a person who had custody of a seized item to request that police photograph or copy it (subject to exceptions where this would prejudice an investigation).^[5] In some cases, this may allow the physical device to be returned sooner while police retain a forensic image of the data. Whether this applies depends on the circumstances of the investigation.

If you are released under investigation (RUI) or on bail, police may continue to hold your phone even after you leave custody, provided retention remains necessary.

Getting Your Phone Back

PACE section 22 limits retention to what is necessary in all the circumstances.^[4] PACE Code C requires that property withheld from a detainee (for example because it is needed as evidence) should be returned on release from custody unless there is good reason to retain it.^[9] If you have been released without charge, you should ask for your phone back. If police refuse, request the reason in writing and keep a record of when the phone was seized and who seized it.

If there is a dispute about the return of property held by police, you may apply to a court of summary jurisdiction (magistrates' court) for an order under the Police (Property) Act 1897.^[10] A solicitor can write to the investigating officer or custody officer on your behalf and, if necessary, make a court application.

What Data Can Police Access on Your Phone?

If police lawfully examine your phone — whether by you unlocking it, through forensic tools, or following a RIPA notice — they may access a wide range of material, including:

• Call logs and contact lists
• SMS, WhatsApp, Signal and other messaging apps
• Social media activity (Facebook, Instagram, X/Twitter, Snapchat, etc.)
• Photographs and videos stored on the device
• GPS location history and map data
• Internet browsing history and search queries
• Emails and calendar entries
• Banking and payment app data

This data may be compared with your account in a police interview. If you are questioned about phone evidence, having a solicitor present is essential. See our guide on police interview rights for more information.

Practical Advice If Police Take Your Phone

• Ask what power is being used:different powers have different rules. Note the officer's name, collar number and the stated legal authority.
• Get legal advice immediately: request a solicitor at the police station under PACE section 58. Advice is free and not means-tested.
• Do not unlock voluntarily: unless your solicitor advises you to, do not enter your PIN or password without understanding the legal consequences.
• Check for a RIPA notice: ask whether a formal section 49 notice has been served.^[7]
• Document everything: note the date, time, location, device make and model, and any property receipt given by the custody officer.
• Request return in writing: once the investigation concludes or if you believe retention is no longer necessary, write to the officer in the case asking for your phone back.^{[4] [9]}
• Remote wipe and cloud backups: do not attempt to remotely wipe your device while it is in police possession — this may interfere with an investigation and could have legal consequences. Take advice before changing passwords or deleting cloud accounts.
